The Chinese word **认证 (rènzhèng)**, meaning "certification" or "authentication," is a compound formed through the combination of two meaningful characters: **认 (rèn)**, which means "to recognize" or "to acknowledge," and **证 (zhèng)**, which means "proof," "evidence," or "to certify." Together, they create a verb-object (or resultative) relationship where the action of **认 (recognizing)** is directed towards the object **证 (proof)**, thus conceptually meaning "to recognize as proof" or "to verify and confirm," which perfectly encapsulates the modern meaning of an official process to certify or authenticate something.
